To all "whom it may concern:

F 2 is an enlarged view of the lifting mechanism. i I

The mechanism employed for the purpose above mentioned, includes adapted to be arranged transversely of the chassis of a motor vehicle, resting upon the opposed side members '11 thereof.

frainerlO upon the chassis ofthe machine The frame 10 isprovidechwith a central bcaring lii for the lower end of a vertically disposed screw 14: adapted to be rotated by meansof a bevel gear-"15 carried by the screw'and meshingiwith itfSlIIlllftI gear 16 mounted upon the adjacentend of an operating shaft'il7. .ThexshaftlT-is of course disposed at i right angle to the screw, and

operatesdri -bearings 18 provided" by the frame 10;". A crank'lhandle lS) having de "tachable associations. 2 with "the operating shaft 17, 'is sutilizedt for rotating the latter.

The wagonbody engaging element includes a nut-i0 threadedly' I associated with the screw 13 to'-travel --longitudinally thereof when the screw is rotated, a pair of bracket arms Ql'being 'carried by the nut 20 and designed to secured "to the bottom-and adj acentjentl walls 7 of i the wagon body: A to 'bew'liftedif Inpractice, when it-is' desired itoirelervatethe body A with afVlSWL of emptying the I contents, the shaft: 17 is rotatedi'to r'imparti a similar movement to the screw 14 through-the instrumentality I of theh'evel-gearingr As thewscrewd l is rotated; the nut 20 travels longitudinally ofthe screw and thebody A tilted; w

*As the bodyuA' i's 'e1evated,--the' screw 14'- 'assumes an inclined positionlwith :respectto the frame 10,' and is consequently subjected to severe lateral strain under the weight :of

the 'load'e-dfwag'on body. It. frequently pens under:v such conditions the screw 14; is-bent or brokemuand' in order to obviate these difficulties, I makeuse of: an inverted substantially u shaped frame which straddles the screw 13 as shown, the cross piece 23 of the frame constituting a bearing for the adjacent end of the screw 14. The par- 1 all'el limbs. 24: of the frame are provided with openings adjacent their free ends, the opening of one of-the limbs loosely receiving the operatingshaft 17, and having its free endarranged-between the beveled gear 16 andpne of the bearings 18 for the shaft.

The opening inthe other limb ofv the frame I registers with an opening in a lug 24 rising from the frame 10,- and-passed through said opening is "a pivot 'bolt 25 havinga nut 26 7 associated therewith to hold the parts operatively connected. A plate 27 is arranged Y transversely-between the limbs 23 of the frame and has its opposite ends bent upwardly as at 28 and secured to the. limbs of the frame in any suitable manner. 'The plate27-l1as opening the receptionfot the screvv'l i and constitutes a hearing for the latter. -Reinforcing bars "30 and 31 respectively have their corresponding upper extremities secured in any suitable manner to the limbs of the frame, thebars being divergently disposed and'hav'e' their opposite ends pivotally mounted to swing with the trance and the screw 14: as a unit to anv inclined positionzwhen the body Alis elevated. For this purpose, the bar .30 hasi its lower extremity formed to provide acollar' 32.100sely embracing the.operating shaft 17 and disposedf in juxtaposition Ito'the outermost bearing 18 fortheshaft.
